Currently i've started with building a XVIIb, i'll fill you in from the start.
The drawing i've used and the ribs to make the styrodure parts.
All blocks of styrodure are ready and glued together on the jigg.
Used cheap wallfiller to get the final shape.
The ribs and the endresult for making the conningtower, she still has to be prepared for filling and sanding.
